The U.S. Supreme Court says it won't hear a case challenging California's 10-day waiting period for firearm purchases.
California's waiting period is one of the longest in the nation. It was created so authorities have time to do background checks and in case a person is trying to by a gun to do harm.
But petitioners argue the state's full "cooling off period" shouldn't apply to "subsequent purchasers," or people who already own a firearm.
Justice Clarence Thomas dissented the Supreme Court's decision. He said its inaction is a signal the Second Amendment is "a disfavored right in this Court."
